Investigators say Bryan and his friend, Corey Steplight, 14, wanted Mason's Grand Prix with fancy rims. Orange County Sheriff's deputies nabbed them hours later taking wheels off the car near Corey's home on 24th Street. Both teens were charged with first-degree murder. Corey's case is still headed for trial but prosecutors hope to work out a plea deal, said Assistant State Attorney Robin Wilkinson.

Mason's family was in court for the sentencing.

"I'm glad we have a conviction," said Mason's stepfather, Gerald Polk. "Right now we can have some type of closure." But he urges officials to change the juvenile system to hold teenagers more accountable for their crimes before it reaches a deadly situation. Both Corey and Bryan have juvenile records.
